Boko Haram is an Islamist militant group, operating in the western and central African region, which has pledged allegiance to the Daesh terrorist group. Militants oppose Western civilization's model of education and seek the introduction of sharia law in Nigeria. The group's ultimate goal is to establish the Islamic caliphate in Nigeria. Boko Haram is responsible for most terrorist attacks and abductions in the country.
Alongside with Nigeria, Niger, Cameroon and Chad are jointly carrying out a military campaign to battle the Islamists.
